Hello,

I have been using a 2450 SMU to take IV sweeps on LED's, but now I need to be able to measure voltage across a photodetector at the same time.

I have a TSP script that I wrote for running the IV sweeps, and I have a 2nd 2450 that I can use to take the voltage, but how do I configure the 2nd SMU to take the voltage at the same time?

Here is the TSP script that I have been using

reset()
smu.source.protect.level = smu.PROTECT_2V
smu.source.ilimit.level = 0.05
smu.measure.autorange = smu.ON
smu.source.readback = smu.ON
smu.measure.autozero.once()
smu.source.sweeplinearstep("IVSweep",-1.0,1.0,0.01,0.00,1,smu.RANGE_AUTO,smu.OFF,smu.OFF,defbuffer1)
smu.measure.terminals = smu.TERMINALS_REAR

I'm sure this is a simple question to answer, but I'm new TSP
